# true-case-path
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
`trueCasePathSync(<fileSystemPath>)`
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
Given a possibly case-variant version of an existing filesystem path, returns
|
||
|
|
the case-exact, normalized version as stored in the filesystem.
|
||
|
|
|
||
|
|
If the input path is a globbing *pattern* as defined by the 'glob' npm
|
||
|
|
package, only the 1st match, if any, is returned.
|
||
|
|
Only a literal input path guarantees an unambiguous result.
|
||
|
|
|
||
|
|
If no matching path exists, undefined is returned.
|
||
|
|
On case-SENSITIVE filesystems, a match will also be found, but if case
|
||
|
|
variations of a given path exist, it is undefined which match is returned.
|
||
|
|
|
||
|
|
## Platforms
|
||
|
|
|
||
|
|
Windows, OSX, and Linux (though note the limitations with case-insensitive filesystems).
|
||
|
|
|
||
|
|
## Limitations
|
||
|
|
|
||
|
|
- Paths starting with `'./'` are acceptable, but paths starting with `'../'`
|
||
|
|
are not - when in doubt, resolve with `fs.realPathSync()` first.
|
||
|
|
An initial `'.'` and *interior* `'..'` instances are normalized, but a relative
|
||
|
|
input path still results in a relative output path. If you want to ensure
|
||
|
|
an absolute output path, apply `fs.realPathSync()` to the result.
|
||
|
|
- On Windows, no attempt is made to case-correct the drive letter or UNC-share
|
||
|
|
component of the path.
|
||
|
|
- Unicode support:
|
||
|
|
- Be sure to use UTF8 source-code files (with a BOM on Windows)
|
||
|
|
- On OSX, the input path is automatically converted to NFD Unicode form
|
||
|
|
to match how the filesystem stores names, but note that the result will
|
||
|
|
invariably be NFD too (which makes no difference for ASCII-characters-only
|
||
|
|
names).
|
||
|
|
|
||
|
|
## Examples
|
||
|
|
|
||
|
|
```
|
||
|
|
const trueCasePathSync = require('true-case-path')
|
||
|
|
|
||
|
|
trueCasePathSync('/users/guest') // OSX: -> '/Users/Guest'
|
||
|
|
|
||
|
|
trueCasePathSync('c:\\users\\all users') // Windows: -> 'c:\Users\All Users'
|
||
|
|
```
